Application filed October 5, 1915. Serial No. 54,208.

To all whom it may concern:

Be it known that I, ALoNZo E.RHOADES, a resident of Hopedale'in thecounty of Worcester and State of Massachusetts, have invented certainnew and useful Improvements in Automatic Weft-Replenishing Looms, ofwhich the following is a specification.

In automatic weft replenishing looms wherein the replenishment iseffected by ejecting a spent weft carrier from the shuttle and insertinga full weft carrier in the shuttle (as in the well-known Northrop orDraper loom, as exemplified, for example, in United States LettersPatent of Northrop No. 529,940, November 27, 1894:) it is important thatno transfer of weft carriers should be made except when the shuttle isin the proper position in the shuttle box at the weft replenishing sideof the loom. If the shuttle is not in the proper position when thetransfer of weft carriers takes place breakage is apt to occur.

The object of the present invention is to insure the shuttle being inthe correct position in the shuttle box at the replenishing side of theloom when the transfer of weft carriers takes place. If the shuttle isnot in the correct position, mechanism is provided which prevents theaction of the transferrer' so that no transfer of weft carriers takesplace and consequently no breakage can occur.

The preferred embodiment of the present invention is illustrated in theaccompanying drawings wherein- Figure 1, is a plan view of the shuttlebox at the replenishing side of the loom. Fig. 2, is a front view of thesaid shuttle box. Fig. 3, is a vertical section through said shuttle boxillustrating also so much of the transferrer and the magazine for filledbobbins as is necessary for an understanding of the present invention.Fig. 4, is an end view of the said shuttle box.

Referring to the drawings, A, is the lay; B, is the shuttle box at thereplenishing side of the loom; C, is the shuttle; D, is a weft carrierin the shuttle; E, is a portion of the rotary magazine containing filledweft carriers F; G, is the swinging transferrer; H, is the transferrerdog pivoted on the lower arm of the transferrer and I, is the bunter onthe lay which cooperates with the transferrer dog H. All of these partsare similar to those shown in the aforesaid Northrop Patent No. 529,940.During the normal running of the loom the transferrer G, occupies itselevated position shown in Fig. 3, ready to co-act with the spare weftcarrier F, beneath it. The transferrer dog H, during the normal runningof the loom occupies the position shown in full lines in Fig. 3, whereit is beyond the reach of the bunter I, when the lay swings forward.When replenishment is required, the exhaustion or approaching exhaustionof the working weft is detected by one of the detectors such as arecommonly employed in this class of looms, and the transferrer dog H, isswung upwardly so that its notched end J, is brought into the path ofthebunter I, on the lay. Hence, when the lay swings forwardly the bunterencounters the dog H, and swings it to the position illustrated in thedotted lines shown in Fig. 3. This is accompanied by a downward swing ofthe transferrer G, which inserts a filled weft carrier in the shuttle C,and ejects the spent or nearly spent weft carrier D. This is thecustomary action of the Northrop loom and has long been well known.

The drawings also illustrate the usual picker K, and picker stick L, atthe replenishing side of the loom.

When the shuttle has entered the shuttle box at the replenishing side ofthe loom it may not occupy the correct position, and the illustratedmechanism is such that in that event the transferrer dog H, will not be0peratively encountered by the bunter I, and the transferrer G, will notact.

As shown in Fig. l, a horizontal lever M, is pivoted at a, to theshuttle box at the replenishing side of the loom and it extendsforwardly outside of the picker K. The lever M, at its middle isprovided with an abutment N, which is directly in the path of the outerend of the picker K. At its front end the lever M, is pivoted at b, to afiector P, is downwardly and rearwardly in-V clined. The hunter 1, isprovided with. a

downwardly extending projectionlt, which likewise has its front face 6,downwardly and rearwardly inclined. The hunter proper I, also has, asshown, a downwardly and rearwardly inclined face f. As shown in Pig. 3,the inclined faces d, e, and f, are all in the same plane. 7

Fig. 1, shows the shuttle at its proper position in the shuttle box toreceive a fresh weft carrier. As here shown its outer end bears againstthe picker K, and the picker in turn bears against the abutment N, onthe lever M. As a consequence the deflector P, occupies its extremeouter position with the inner end of the slot 0, against the shank ofthe screw stud Q. The shuttle cannot be driven outwardly any fartherthan is shown in Fig. 1. because the stud Q, prevents any' furtheroutward movement of the shuttle.

V i Vhen the deflector P, occupiesthe position lifted as the result ofthe detection of ex haustion or approaching exhaustion of the workingweft, the hunter 1, encounters the elevated transferrer dog and thetransfer is effected.

hen the shuttle is driven out of the shuttle box at the replenishingside of the loom a spring S, swings the lever M, inwardly until theouter end of the slot 0, encounters the shank of the screw'stud Q3.

he deflector P, then covers the hunter 1.

Should the shuttle, on arriving at the shuttle box at the replenishingside of the loom when a transfer should take place, not enter the boxfar enough to swing the lever M, outwardly, the deflector P, will beleft in a position covering the hunter 1, and with its inclined face (Z,in register with the uplifted transferrer dog Pf. Consequently, when thelay swings forward, the inclined face (Z, of the deflector encountersthe transferrer dog and, as the result, the transferrer dog is swungdownwardly, turning on its pivot g, instead of the transferrer G, beingswung on its pivot 71,. During this downward swing of the transferr-erdog H, on its pivot y, it rides down the inclined faces (Z, f, and c, tothe position shown in full lines in Fig. 3. I The-customary springconnections between the transferrer dog H, and its actuating mechanismpermit this downward swing. Consequently, the transfor cannot take placeuntil the deflector P,

is entirely removed from the path of the transferrer dog Pf. It isobvious that the deflector P, must he moved outwardly far enough to heout of reach of any portion of the rear face of the transferrer dog H,before the transferrer dog can he operatively engaged by the hunter 1.The organization of the deflector P, and its actuating devices ispreferably such that the hunter I, cannot operatively engage the.transferrer dog H, unless'the deflectorrP, is moved to its extreme outerposition with the inner end of its slot 0, against the shank of thescrewstud Q, as'illustrated in Fig. 1. position of the shuttle in theshuttle box for the reception of the incoming weft car- This insures theexact proper rier. The shuttle cannot move outwardlyi any fartherbecause the deflector P, is at its extreme outer position. Any failureof the shuttle to reach this extreme outer position results in thedeflector P, obstructing the transferrer dog H, and Preventing itsoperative connection with the hunter 1. i
